Abstract: An actuator housing intended to provide haptic feedback in a vehicle includes a container having a recess configured to accommodate an oscillating actuator and an insertion opening that opens into the recess, and a cover configured to at least partially close the insertion opening of the container. The container and the cover are mounted so as to be able to move in translation relative to each other and configured such that, when the oscillating actuator is accommodated in the recess, the oscillation of the oscillating actuator causes the cover to move in translation relative to the container, generating haptic vibration in a direction of movement.

Abstract: A fraction of a fluid mixture of two non miscible phases carried in a pipe (2) is tapped by a conduit (4), pressurized by a pump (6) and reinjected by nozzles (22, 24) to form jets which spray the drops of the discontinuous phase. For this purpose, these jets are installed like bars on a grid barring the pipe (2) with opposed jets of the discontinuous phase striking each other to ensure droplet formation.
